Meaning that you could only enjoy limited life with the Lord on this Earth. No eternal life, just this one.
For some people, some Christians, it seems Heaven has already started for them here. They walk so close to God everyday. They are in love. And I respect that a lot. I think these people aren't so much focussed on the reward of heaven. They love the Lord so much now, they are just happy to serve Him now in this earthly life. Their reward is now.
I'm thinking that is a healthy approach. Because if our motivation to follow the Commandments and serve the Lord, is an extrinsic reward like Heaven, we are not really motivated by love. We are motivated by what is in it for us.
"Maybe the Heaven idea was created for those having a real tough time of it here" That seems to suggest man created the idea of Heaven, is that your belief ?
Can people rationalize Christian doctrines by thinking alone and doubting the word of God, without Biblical reference and, still be relevant to understanding God who is unfathomable ?
I don't think so. It seems a pointless question; if there is a God then there is Heaven, and most people are here on CF because they are more than convinced God exists and has a plan for his children, whom He created.
I understand the question but to entertain it as a valid question would show God that I am not a trusting believer in His plan, which I am.
Regardless of how hard things may be, if we doubt and questions God's plan, we have little faith, and He see's all. Heaven is a quarantine house for God, Holy Spirit, Jesus, and chosen souls to abide.
Was the word of God sent to deceive you from Hell ? No, it was to save you from Hell ! As was Yeshua/Jesus - Rest assured !
